Charlie Dimmock and the Rich Brothers are in Bedford, competing to design a garden for busy single mum Sam and her six-year-old daughter Amy.

Charlie Dimmock and the Rich brothers are off to Farnham in Surrey to meet James and his fiancee Laura, a young couple with a long, thin garden that's a total disaster. It's completely bare apart from theremains of an old bathroom suite - not a plant or flower in sight.
